WHEEL.

SPECIFICATION forming part of Letters Patent No. 482,866, datedSeptember 20, 1892. Application filed August 17, 1891. Serial No.402,823. (No model.)

To all whom it may concern:

Be it known that I, THEODORE O. MUNZ, of Toledo, county of Lucas, andState of Ohio, have invented certain new and useful Improvementsin MetalWheels; and I do hereby declare that the following is a full, clear, andexact description of the invention,which will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the figures of reference markedthereon, which form part of this specification.

My invention relates to metal wheels of that character used in bicycles,tricycles, childrens carriages, &c., and has especial relation to theconstruction of the hub-disks, whereby great strength is insured withlightness of metal and economy of construction, a further object beingto construct a wheel of neat appearance and few parts.

Heretofore wheels have been constructed the hubs of which, being inseveral pieces and the several modes of fastening the spokescomplicated, requires great expense in assembling the same. My object isto form a simple, effective, and inexpensive wheel that shall subservethe same purpose as the more complicated ones.

In the drawings, Figure 1 illustrates a vertical section of the hub andspokes, showing the manner of holding the spokes in place. Fig. 2 isaniinside end view of the hub-disk, and Fig. 3 is an outside end view ofthe same. Fig. 4 is a section in detail of an additional means ofholding the spokes in place.

I will now proceed to describe the wheel in detail, like numerals ofreference indicating like parts throughout the several views.

1 designates the thimble,which is of the ordinary construction, having abead to hold the hubs apart, on the ends of which are the hubdisks 2.Each hub-disk 2 is formed of a web 3, sand-band 4, and bearing 5 for thethimble, all in one piece. On the web 3 are formed integral rings6,whicl1 serve to hold the spokes from side movement.

7 designates radial openings in the web, extending from thecircumference to the center of the hub, in which spokes 8 are passed,the lower portion of the bearing5 having a curved recess 9 to allow ofthe spokes being'bent therein, as will be described.

In assembling a hub to form a wheel the spokes 8 are first inserted, theends projecting into the central orifice a short distance. A punch isthen inserted, which first bends the ends into the recesses 9, when theends are cut oif, making a smooth bore for the insertion of the thimble1, which may be slightly expanded at the ends to secure the disks frommovement thereon. It will be seen that the spokes are held firmly in anydirection of tension, as the turned end within the recess 9 holds thespokes from displacement by outward tension, and the thimble fittingsnugly against the same prevents an inward movement, while the radialopenings are of a size to hold the spokes closely therein and preventlateral or side movement. In order to hold the spokes more firmly, I maybend the rings down so that they impinge into the spokes (see Figs. 4and 10) without departing from the spirit of my invention. Thus it willbe seen that I provide a wheel simple of construction, durable in use,and cheap of manufacture.

What I claim is- 1. In a metal wheel, hub-disks formed of a single piecehaving a web, a central opening therein, a sand-band concentric with thesame, and rings upon either side of the Web concentric to the centralopenings, in combinatien with spokes passed between the rings and havingtheir ends upset within recesses formed Within the web.

2. A metal wheel formed of a thimble, a disk upon each end thereof, eachdisk c0mprising, in a single piece, a web, having a central opening forthe insertion of the thimble, recesses formed concentrically of thecentral opening and leading thereto for the reception of the inner endsof the spokes, radial grooves extending from the recesses to theperiphery, rings upon each side of the web, and spokes arranged, theends being forced, at an angle ifito the recesses and resting upon thethim- In testimony that I claim the foregoing as my own I hereby affixmy signature in presence of two witnesses.

It is'hereby certified that in Letters Patent No. 482,806, grantedSeptember 20 1892, upon the application of Theodore G. Munz, of Toledo,Ohio, for an improvement in Wheels, an error appears in the printedspecification requiring the following correction, viz.: In line 72, theparenthetical clause See Figs. 4 and 10, should read See Fig. 4 at 10and that the Letters Patent should be read with this correction thereinthat the same may conform to the record of the casein the Patent Office.
